context_page_description: The Prince Edward Islands are two small islands in the subantarctic Indian Ocean that are part of South Africa. The islands are named Marion Island and Prince Edward Island.
  The islands in the group have been declared Special Nature Reserves under the South African Environmental Management: Protected Areas Act, No. 57 of 2003, and activities on the islands are therefore restricted to research and conservation management. Further protection was granted when the area was declared a marine protected area in 2013. The only human inhabitants of the islands are the staff of a meteorological and biological research station run by the South African National Antarctic Programme on Marion Island.
context_section_description: The islands are part of the Southern Indian Ocean Islands tundra ecoregion that includes a small number of subantarctic islands. Because of the paucity of land masses in the Southern Ocean, the islands host a wide variety of species and are critical to conservation. In the cold subantarctic climate, plants are mainly limited to grasses, mosses, and kelp, while lichens are the most visible fungi. The main indigenous animals are insects along with large populations of seabirds, seals and penguins. At least twenty-nine different species of birds are thought to breed on the islands, and it is estimated the islands support upwards of 5 million breeding seabirds, and 8 million seabirds total. Five species of albatross (of which all are either threatened or endangered) are known to breed on the islands, including the wandering albatross, dark-mantled, light-mantled, Indian yellow-nosed and grey-headed albatross. The islands also host fourteen species of petrel, four species of prion, the Antarctic tern, and the brown skua, among others seabirds. Four penguin species are found, including king penguins, Eastern rockhoppers, gentoos and macaroni penguins.
  Three species of seal breed on the islands, including the southern elephant seal, the Antarctic fur seal, and the Subantarctic fur seal. The waters surrounding the islands are often frequented by several species of whale, especially orcas, which prey on penguins and seals. Large whales such as southern rights and southern humpbacks, and leopard seals are seen more sporadically, and it remains unclear how large or stable their current local populations are, though it is thought their numbers are significantly down compared to the time of first human contact with the islands. The area saw heavy sealing and whaling operations in the nineteenth century and continued to be subject to mass illegal whaling until the 1970s, with the Soviet Union and Japan allegedly continuing whaling operations into the 1990s. Currently, the greatest ecological threat is the longline fishing of Patagonian toothfish, which endangers a number of seabirds that dive into the water after baited hooks.
